[In Progress]
The CMUCL project is pleased to announce the release of CMUCL 20f.
This is a major release which contains numerous enhancements and
bug fixes from the 20c release.
CMUCL is a free, high performance implementation of the Common Lisp
programming language which runs on most major Unix platforms. It
mainly conforms to the ANSI Common Lisp standard. CMUCL provides a
sophisticated native code compiler; a powerful foreign function
interface; an implementation of CLOS, the Common Lisp Object System,
which includes multi-methods and a meta-object protocol; a source-level
debugger and code profiler; and an Emacs-like editor implemented in
Common Lisp. CMUCL is maintained by a team of volunteers collaborating
over the Internet, and is mostly in the public domain.
New in this release:
* Known issues:
* Feature enhancements
* Changes
* Update to ASDF 3.0.3.
* When *PRINT-CASE* is :DOWNCASE, integers are printed with
lowercase letters when needed.
* Micro-optimize KERNEL:DOUBLE-FLOAT-BITS for x86/sse2.
* Add micro-optimization for unary FTRUNCATE for x86/sse2.
* Compiler can derive the types of the results of DECODE-FLOAT.
* ANSI compliance fixes:
* Bugfixes:
* Trac Tickets:
* Other changes:
* Improvements to the PCL implementation of CLOS:
* Changes to building procedure:
This release is not binary compatible with code compiled using CMUCL
20e; you will need to recompile FASL files.
